Abstract
Abstract A tape player for recording and reproducing sound. It is characterized in that it includes a first motor adapted to drive both a take-up reel and a capstan and a second motor which is selectively operated to drive said take-up or feed reel at high speed for fast forwarding or fast rewinding of the tape. Said selective operation is performed by gearing means including a second motor pulley, a sun gear, a second drive belt passed around the second motor pulley and the sun gear, a planet gear in mesh with the sun gear and a rocker arm to swing the planet gear between the feed and take-up reels. There is also provided a tape player having a group of feather touch type push buttons for recording, reproduction, fast forward and rewinding and switching off whereas only cassette ejecting operations are performed by mechanical means.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
86 words
A tape player for recording and reproducing sound comprising a feed reel and a take-up reel a capstan; a first motor adapted to provide a first driving force; first gearing means for transmitting said first driving force both to said take-up reel and said capstan; a second motor adapted to provide a second driving force; second gearing means for transmitting said second driving force selectively to one of the take-up reel and feed reel at high speed for fast forwarding or fast rewinding of the tape.
Claim 2
Dependent Claim
86 words
A tape player for recording and reproducing sound comprising a feed reel and a take-up reel a capstan; a first motor adapted to provide a first driving force; first gearing means for transmitting said first driving force both to said take-up reel and said capstan; a second motor adapted to provide a second driving force; second gearing means for transmitting said second driving force selectively to one of the take-up reel and feed reel at high speed for fast forwarding or fast rewinding of the tape.
Claim 3
Dependent Claim
66 words
A tape player according to claim 1, wherein said first gearing means includes a first motor pulley connected coaxially to said first motor; swingable pulley means; a flywheel connected coaxially with the capstan; a first drive belt passed around the first motor pulley, the swingable pulley means, and the flywheel; and means for actuating said swingable pulley into and out of engagement with the take-up reel.
Claim 4
Dependent Claim
59 words
A tape player according to claim 2, wherein said swingable pulley means includes a swingable pulley, a swiveling lever diametrically extending relative to said swingable pulley and having a first end, a middle portion, and a second end; said middle portion coaxially secured to said swingable pulley, said swiveling lever being adapted for pivotal movement about said first end.
Claim 5
Dependent Claim
69 words
A tape player according to claim 3, wherein said actuating means includes a setting plate slidable with respect to the chassis, said swiveling lever being urged toward the take-up reel, said setting plate being in contact with the swiveling arm at said second end thereof, said setting plate being slidable in two opposite directions to give way to said urge of the swiveling lever and to counteract the same.
Claim 6
Dependent Claim
20 words
A tape player according to claim 4, wherein said actuating means further includes locking means for locking said rocker arm.
Claim 7
Dependent Claim
68 words
A tape player according to claim 5, wherein said locking means includes a cam plate actuated by said plate, a play arm swingably mounted on the chassis to follow said cam plate at a first arm end thereof, a restriction plate actuated by said play arm to lock said rocker arm whereby the planet gear is retained out of engagement with the feed reel and the take-up reel.
Claim 8
Dependent Claim
69 words
A tape player according to claim 1, wherein said second gearing means includes a second motor pulley connected coaxially to said second motor, a sun gear, a second drive belt passed around said second motor pulley and said sun gear, a planet gear in mesh with said sun gear, and a rocker arm adapted to swing said planet gear between said feed reel and said take-up reel for engagement.
Claim 9
Dependent Claim
32 words
A tape player according to claim 7, wherein said locker arm is adapted to be locked to retain the planet gear out of engagement with the feed reel and the take-up reel.
